Ensemble forecasts from the Israel Meteorological Service and global models currently point to a daytime maximum near 30°C in Tel Aviv on May 18, establishing that outcome as the market leader at 40% implied probability. A strengthening high-pressure ridge over the eastern Mediterranean is driving subsidence, strong solar heating, and limited cloud cover that should allow surface warming above the seasonal late-spring average of 26–28°C. Minimal sea-breeze moderation through midday is expected to amplify peak readings. Recent model runs have converged on this range, with final updates and real-time observations from Ben Gurion International Airport poised to refine the exact high before resolution.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column on the specified date once information is finalized for all hours on that date, available here: https://www.weather.gov/wrh/timeseries?site=LLBG
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve to "Yes" until data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
